Laser ranging structure and operation process
The base part is a light emitter, which is your laser pointer. You also need a light receiver, a switch to control the light emitter, and a timer.The operation process is as follows: turn on the light transmitter to prompt the initial timing -- the light runs out, meets the reflective object and comes back -- is received by the light receiver with the timer interrupted timing. And then the calculation, light has a velocity, which you must know, let's say it's two seconds from declaration to reversal, what is the object going to be?Yeah, about 300,000 kilometers. Advantage the time into digital output, directly to the laser ranging is not demand DA conversion process of resolution can be as high as 65 ps, the conversion from the single measurement precision is 0.98 cm two stop channel can be measured with each measurement channel four pulse 1 MHZ continuous measurable data output rate QFN32 encapsulation, small volume, especially for hand-held laser range finder operating temperature planning: - 40 ° C to + 125 ° c. 8. Ultra-low power consumption.
Suppose you choose a measurement plan, take a measurement and a calibration every second, and when the power supply is 5V, the current consumption is only 3uA, which makes the tdc-gp2 particularly suitable for the hand-held rangefinder. In recent years, the high-speed direction of opening, the number of ships and water traffic density and the number of dangerous cargo loading increasing, collision of ships from time to time, the severe threat to ship flight safety and Marine ecological environment. It is imperative to develop an efficient collision avoidance system to protect the talents of moving ships.This system planning based on the high cost performance, according to start sea practice environment, use sophisticated laser measurement technology, the end of the collision avoidance system is the key technology of ranging technology is the key technology of ship collision avoidance system, this paper chooses laser ranging sensor and has two degrees of freedom yuntai, using high function of the single chip microcomputer control, the end of the horizontal and vertical direction of a full range of dynamic scanning, real-time independent monitoring policy boat and ships around the distance, the domain of ships and policies set by the distance of the ship arrived at a safe distance, sound and light alarm system alarm circuit is over,Prompt operators to adjust the ship's route in time, and conduct corresponding avoidance and other processing.
Mistakes of purchasing laser rangefinders
Buy laser rangefinder is having those mistakes?At present, the customer purchases the product to be able to have many erroneous zones, the surveying and mapping profession is no exception, the micro measurement technology now the customer purchases the laser rangefinder the common easy to make the erroneous zone to list as follows:
1. think "domestic" is inferior to "foreign"
This is a misconception not only in laser rangefinders, but also in other products.Indeed, in some products, our country still can not meet some "foreign goods" high function and high goal requirements. But in the ranging profession, our country and the international almost on the same starting point, has been very mature, and "foreign goods" compared to our "domestic goods" not inferior, and in the price also has certain advantages.So if you are a surveying and mapping professional users, you want to buy a laser rangefinder, no harm to take a test.
2. Blindly seek high goals
Many products have technical goals, and high goals often mean relatively high utility.Laser rangefinders have two common technical objectives - range and accuracy. In recent years, range and precision of the abnormal speed fast, often months apart, Michael laser rangefinder measurement range and precision of the new product will ascend to a new step, surveying and mapping professionals think many want to let your product time to keep forward, surely there must be people, so when the choose and buy blindly seek large range and high precision.
Actually do so a lot of time is a kind of mistake area, when the user is in choose and buy, should be to choose range finder according to oneself actual demand, if be the range finder that average individual user applies, can according to the far and near of range finder dimensions, and to the requirement of measurement precision, can choose appropriate range finder with precision. If be unit choose and buy, expect to be applied as project ranging, requirement precision is tall, measure range is far, even still need to use the function such as measure point of view, area, volume, temperature, so the product that measure is very appropriate.
3. Blindly seek high prices
The price of laser rangefinder in the market is very chaotic, many products have this phenomenon, so many users in the purchase is relatively consistent that the high price of the product is good, blindly seeking high price, regardless of the function and whether suitable for their own use.When you buy the real thing, you suffer. You have to spend money from scratch.Price is now of utmost importance to customers.So when the purchase of laser rangefinder to pay attention to, ranging scale, ranging accuracy, measured how much, function, lens, multiple, laser, bad conditions, etc.Price is not the point, the point is the product, see their own use to the decision.If you are the person that a surveying and mapping profession USES, do not prevent to see the product function that is measured laser range finder, the laser range finder that applies on choosing appropriate project.
